Talk:Derived category/Comments

From Wikipedia, the free encyclopedia

Should have importance one level below that of homological algebra (hence now Mid). Should add examples of applications (e.g., Verdier duality in topology, Grothendiecks general duality theorems in algebraic geometry (incl. étale cohomogy), solution functors in D-module theory). Should explain the major simplification brought about by derived categories compared to spectral sequences when dealing with composite functors (e.g., derived category Künneth formula compared to EGA III hypertor spectral sequences).
